Cruise staffer: "Go back to your rooms"

An Italian television station made public Thursday new amateur video showing a staffer of the cruise ship that last week ran aground off Tuscany urging a hallway full of passengers in life jackets to return to their rooms.

The Costa Concordia crew member tells passengers "everything is under control," according to the British Broadcasting Corp.'s translation of the video, during what appears to be the beginning of the disaster that has left at least 11 people dead and 21 unaccounted for. The video was posted by Italy's Rainews24, which can be watched in Italian here.

"But I'm kindly asking you to go back to your rooms, where you'll be seated and tranquil. Everything is under control."

The amateur video came to light hours after an audiotape emerged in which a crew member told an Italian port official that the ship was only experiencing a blackout 30 minutes after the accident that resulted in the cruise liner keeling over.
